PANY, 0F CINCINNATI, OHIO, .A. CORPORATION OF OHIO WEB ALIGNING AND TEN SIGNING DEVICE Original No. 1,610,599, dated December 14, 1926, Serial No. 24,885, filed. April 21, 192 5. Application for reissue filed May 12, 1927. Serial No. 190,941.

This invention is particularly intended for usage in connection with such machines as manifolding typewriters and the like and s designed with'the object of producing a device in which perfect registration of a serles of superposed form-printed webs may be obtained, together with the advantages to be obtained by a measured delivery feed 1n which all air pockets between ad acent webs are eliminatedand in which perfect impression of the type is secured in printing the superposed forms. A further 0b]ect lies in the elimination of web buckling and wr1nk ling as well as in the prevention thereby of all stencil cutting of the type in printing upon' the superposed webs.- An additional feature lies in the simultaneous provision of a means for cutting the attached printed forms from one another, as a part of the mechanism by means of which web alignment is secured simultaneously with the elimination of air pockets, web buckling, stencil cutting of the type, etc.

These and other objects are attained in the device described in the following specifi= cation and illustrated in the accompanying drawings, in which: 4

The embodiment of the invention has been chosen as having particular adaptation to a. form of typewriter which is in common use and which employs a stationary platen over which a relatively movable typewriter print ing mechanism moves during the writing operation.

However, the use of the invention need not be confined to any particular style of printing mechanism, to any of which it is readily adaptable, but may just as readily be used independently thereof, in which the mere use of hand writing will permit the invention to function to just as greatan advantage. A stand of well known design, has been employed to support the usual stationary platen 9 embodied in this style of stand. Over this platen the usual typewriter 1O operate and etween the platen and the writing mechanism'a series of superposed webs of paper 11 are located. These webs are taken from a source of supply which consists of a suitably mounted roll 12 located beneath the platen. In order to provide for the passage of the webs from roll 12 onto the platen in a manner which constitutes an important feature of the invention, the frame which supports the platen is extended rearwardly as two supporting arms 13 and 14. Between these arms a roller carrying unit is mounted. This unit consists of two side .bars 15 and16 which carry a series of shutters or slats 17 which are rigidly attached to the side bars. Above these slats are locateda series of rollers 18, one roller being located above each slat. Each end of each roller is located ina slot 22 located above each end of each slot, the slot being inclined upwardly from its rear to the front end as shown. The position of the rollers when at the rear of the slots is such that they rest upon the slats and when they are moved to the front of the slots they are lifted upwardly somewhat to bar is (firovided with lugs 20 which extend upwar y back of the spindles 21 which journal the rollers in the slots 22. -U on each roller spindle a sprin' 23 is fastene the op-,

posite ends of the springs being located back of the spindles somewhatso as to bring about;

a a tendency of the rollers to be held rearwill draw the rollers forwardl wardly yieldingly. Now, in order to bring about the forward movement'of the rollers by creatin a forward movementof each bar, a ro 24 has been provided. This v rod is mounted for the sliding of its ends in L-shaped slots 25 in the side frames, while the ends of the bars 19 have short vertical slots 26 to receive the ends ofthe rod 24 in order to permit the rod to draw both bars forwardly and to lock them in this forward position pressing it downwardly in the slots 26 and the vertical portions of slots 25. Thus,'when movedforwardly, the bars 19 and hold them in this position free of t e slats, as shown-in Fig. 4. The slats 17 which cooperate with the rollers 18 are spaced apart as shown,-and are each provided with a slightly raised and roughene 'spot'27 at each end so that the roller contacts with these spots only.

The purpose of-this will be explained later. In order to support the large roll of multiple wound web stationery 12, which constitutes the subject of application for United States Letters Patent serially numbered 740,869 and cate with their ends extending-forwardly so that after the spaced'apertures 34 of the, webs are placed over these hooks they ma be drawn backwardly without danger. of t em becoming disengaged therefrom, this backward movement being effected in the manner and for-the purpose to be hereinafter described. v

To aid in placing and retaining the web apertures u on the hooks 32 and 33 there has been rovi ed an apertured tearing or cuttin nife 35, the apertures 36 and 37 of which are so placed as to permitthe knife to be brought down upon the platen with the hooks pro ecting through the apertures. This knife is fastened to arms which are pivoted as shown in Figs. 5,6 and 7 so that it may be brought with its sharp edge down upon the forward edge of the p aten, in clamping engagement with the webs thereonand in osit-ion to permit of their being torn ofi a ong this edge after one set of form printed web sections have been filled in and drawn for wardly from the platen to provide a fresh set on the platen. Operation of the knife is secured t rough the foot treadle 38 as" shown in Fig. 7 i v In order to prepare the illustrated embodiment of the invention for operation the first 1 thing necessary is to place the roll of stationery upon the trapeze spindle and to then hang the trapeze upon the hook 31, as shown in Fig. 1. The webs are then unrolled from the roll sufficiently to'permit them to be passed This is accomplished byover the platen. first drawing the rollers 18 forwardly and locking them in this'position by means. of the rod-24. In this positionthe rollers have been brought to and held in the position shownin' Fig. 4, in which a space is opened between each roller and its" cooperating slat. The first web to be then placed upon the platen is'the forwardmost web 39. This web is passed upwardl between the forwardmost roller 18 and t e cooperating forwardmost shutter 17 through thespace 40 which exists between them. The web is then brought forwardly over the roller and laid upon the platen with the apertures-34 at its'end placed over the hooks 32 and 33, and beneath knife 35. Each succeedingweb is then taken andpa ssed between each succeeding cooperating roller and shutter and inturn is laid upon the preceding web which has been placedupon the platen after a strip of carbon paper 41, see

Fig. 8, from a side positioned roll 42, see Fig.

1, has been placed upon the preceding platensupported portion of each web, the apertures 34 1n. the end of each succeeding web bein all the webs have thus been placed in position, the rod 24 is pushed upwardly to release the rollers. This allows the springs" 23 to carry.

the rollers to the rear and to carry with them the portion ofthe webs upon the platen until the'slackness therein has been taken out to 3 brought to engage the hooks 32 and 33. After m0 cause them to lie flat onthe platen. Pulling of the rollers upon only the platen supported portions of the web is occasioned by reason of the web snubbing action which takes place between each roller and its cooperating shutate to'ta e out all slack existing in the platen supported portions and will at the sametime bring about any slight rearward motion necessary to bring the forward edge of each aperture a ainst the hook and thus align the correspon ingly spaced printed forms on the superposed webs. After such a rearward ad-- justment the knife 35 is lowered to clamp the webs together. Thus an additional function of pressing the sheets into intimate contact will vary in spots. Sometimes these inequaL- I points between the edges.

the greater degr is performed, with the result that all air pockets between the superposed webs are removed. Notable advantages resulting from this lie in cc of perfection in rinting' the several copies legibly, both from t e stand point of the clean cut heavyimpression produced as Well as-in thetotal elimination of any tendency for the type of the typewriter to stencil cut through the material of the web.

, Should a roll of stationery, such as hasbeen shown, embodycertain webs which are of a less width than others of the webs, in which event perhaps but one of thealigning hooks 32 or-33 are employed, but one side bar 15 or 16, would perhaps be used as a ide for such narrow webs. In order, there 0 e, to provide for the holding of such narrow webs in the proper posit-ion, .a small guide plate 43 may be se-. cured, as for example beneath the slat over which the narrow web is to pass, as shown in.

' which will'now be described, maybe carried ind now, the purpose of the raised spots 27 of the slats will bedescribed. In all paper stock, andparticularly in-paper stock of cer-' tain grades, there exists considerable bulging or buckling. This is occasioned by the fact that in the making of such paper the quality, weight, and consequent thickness of the web ities occur at intervals along oneedge of a web and sometimes along both edges, while frequentlythey are just as likely to occur at' In such an event any attempt to "pass defective webs of this nature between a'flat surface, such as one of the slats 17 and a stra' ht surface, such as one of the rollers 18, woullfcreate a wrinkled web which would result in imperfect copies, mis-- l ment and possible tearing or crumpling f d ne or more of the superposedlplaten supported portions of the we s. owever, if such a. buckled oredge stretched web be held at points widely separated, so as to allow of freedom of the remainder of the web between these\poin'ts to find its own position, there a can be no wrinklin crumpling, tearing or imperfect copy wor produced on the superposed webs. Such a condition is brought about b the provision of the raised spots 27 of the s ats.

It will now be assumed that the device is in condition to operate and that the webs have been positioned that their superposed rinted forms are all in perfect registration. lhe first thing for the operator to do would be to operate the typewriter in order to fill in the printed forms with the desired data. After this has been done the knife 35 is raised and the. forward edges of the webs are grasped, a notch 44, see Fig. 5, having been provlded to enable the operator to take hold of the webs easily. The assembled webs are then drawn forwardly until the next set of approximately aligned apertures 34 "are reached. These apertures are then placed passed beyondslats 1 or, at least, until the snubbing or gripping-action of the rollers in their respective slots upon the webs, has been relieved to from the roll 12. At this point it may be well to digress sufiiciently to refer to the mannerin w ich the unwinding from the roll is brought about. In accordance with the provi-' sions of the invention involved in the use of roll stationery of this type, the forwardweb 39 is the only web upon which tension is ex-' erted to unwind or propel the roll,' the remaining webs being permitted toseek their own positions in increasingly draped condition, as shown in Fig. 1, so that the action,

out without hindrance. When the web apertures have been placed over the hooks 32 and 33 the webs are released. The rollers have been drawn forwardl as has been described, and will now exert a ackward pull upon the released webs and bring about a snubbing or permit the webs to be fed portions which have been drawn to the front and beyondthe platen are then torn ofi over the knife edge. The device is now in condition for the repeated operation of thetypewriter.

Among additional advantages to be obtained by the device just described is the fact that accurately measured delivery isrendered possible. Another advantage which lies in the clamping and tautholding of the superposed rolled webs is that all humps and other unevenness, such as would occur in folded forms of stationery is OVBICOIDBythUS result- I ing in uniformity of copy work, perfect rinting, and correct alignment of printed orms. I

Another advantage attained by the improved device just described, lies in the elimmation of friction by reason of the two point ping of the webs. upon the spots 27 o t e slats. Friction on the hand pulling oration is thus overcome in this manner. ur-

ther advantage may be mentioned in the provision of the aligning feature in conjunction with the clamping of the webs by the knife. This assures that exact parallelism of the .webs is secured and that for-this reason the cutting edge'of the knife will always be at right angles to the sides of the webs, thus causing right angle cutting of the webs over the cutter blade at each cutting or tearing descrih'edthe invention what the platen, a series of slats correspondingin number to the number of rollers, with each of the slats designed for cooperation with but one ofthe rollers, means for mounting said rollers for movement at an angle to the surface of the slats and cause movement thereof toward and away from the slats, movement away from the slats being caused by the webs in their passage over the platen from the source of supply, and separate means adapted to be brought into action functioning the movement of said rollers toward the slats upon cessation of forward movement of the webs.
